obtaining information related to a resource pool for which at least one of full sensing, partial sensing, or random selection is allowed;

triggering resource selection in a slot;

determining a time interval including Y candidate slots;

performing the partial sensing;

selecting, based on the partial sensing, a sidelink (SL) resource from among SL resources included in the Y candidate slots; and

transmitting, based on the SL resource, first sidelink control information including a bit representing whether or not the first device cannot receive physical sidelink feedback channel (PSFCH) reception,

wherein, based on that (i) the partial sensing is allowed for the resource pool and (ii) the resource selection is triggered by aperiodic transmission, the partial sensing is performed for N slots from the slot and before the first of the Y candidate slots,

wherein, based on that (i) the partial sensing is allowed for the resource pool and (ii) the resource selection is triggered by periodic transmission, the partial sensing is performed for a plurality of slots that are periodically spaced apart from each of the Y candidate slots by a resource reservation period value configured for the resource pool,

wherein a value of N is a positive integer, and

wherein a value of Y is a positive integer.
